Abstract: Disclosed is a titanium or titanium alloy plate rolled in one direction, wherein a lubricating film is coated on the surface and the coefficient of sliding friction of the lubricating film-coated surface is controlled to less than 0.15. The elongation (L-El) of the titanium or titanium alloy plate in the rolling direction and the r value (T-r) in the direction perpendicular to the rolling direction have the following relation (1). (T-r)/(L-El)?0.

Abstract: A liquid crystal display device having an array substrate, a counter substrate and liquid crystal material between these two substrates. The array substrate has a plurality of pixel electrodes and auxiliary capacitors corresponding to each of the pixel electrodes. The auxiliary capacitor has a MOS structure comprising a lower electrode made of semiconductor material, an upper electrode made of metal material, and insulating layer between these two electrodes. The upper electrode has a notch region. Therefore, hydrogen is doped into the semiconductor from the notch region, not only from the edge portion uncovered by the upper electrode. In accordance with this composition, it is possible to reduce the manufacturing cost, to realize high characteristic display, and so on.
